Our first workshop was about making a electronic rolling dice. We used an arduino to program the dice’s behavior and used a printboard with led’s and resistors to actually built the led.
In the picture you can see the dice when it was done, and a little card board cover to make it look a bit better. Later on, we upgraded the packaging of the dice to an old ipod box. We added some soft black foam to make the dice look like an luxury randomize device, see movie. The dice doesn’t has any numbers/indicators on it, we figured that it is clear when the leds are lightened up from left to right that that is the number which you have thrown.
For the programmer, we used an array to store the different options which can be thrown. So when you hold the button, random numbers are shown, en when you release it again the last picked number will be shown. We added this feature to give you the feeling that you are ‘shaking your hand’ before you throw the dice.
